The Western Conference's top seeds allowed their opponents back into the game in the fourth quarter, tying their playoff series 3-3.
The power forward told reporters: "I thought we just made too many mistakes tonight. Giving up 37 points in the last quarter is just too much for us. Defensively, we've got to be a little more solid than that."
The teams play their final game on Sunday, with the winner due to meet the Portland Trail Blazers in the semi-finals.
